美国人唱歌的歌词可能指的是美国国歌《星条旗永不落》的歌词，以下是歌词的中文大意和英文原文：
中文大意：
啊!在晨曦初现时，你可看见
是什么让我们如此骄傲？
在黎明的最后一道曙光中欢呼，
是谁的旗帜在激战中始终高扬!
烈火熊熊，炮声隆隆，
我们看到要塞上那面英勇的旗帜
在黑暗过后依然耸立!
英文原文：
Oh, say, can you see, by the dawn's early light,
what so proudly we hail'd at the twilight's last gleaming？
Whose broad stripes and bright stars, thro' the perilous fight,
o'er the ramparts we watch'd, were so gallantly streaming？
And the rocket's red glare, the bombs bursting in air,
gave proof thro' the night that our flag was still there.
Oh, say does that star-spangled banner yet wave
O'er the land of the free and the home of the brave？
On the shore, dimly seen through the mists of the deep,
Where the foe's haughty host in dread silence reposes,
What is that which the breeze, o'er the towering steep,
As it fitfully blows, half conceals, half reveals？
此外，美国人新年时可能会唱《Auld Lang Syne》，这是一首传统歌曲，歌词如下：
歌词：
Should auld acquaintance be forgot, and never brought to mind？
Should auld acquaintance be forgot, for the sake of auld lang syne.
If you ever change your mind, but I living, living me behind,
oh bring it to me, bring me your sweet loving, bring it home to me.
